HUB.

SPECIFICATION forming part of Letters Patent N 0. 691,735, dated January21, 1902.

Application tiled April 29, 1901. Serial No.57,947. (No model.)

To @di 'Lu/tom t may concern: d

Be it known that LJOHN CALVIN WORKING,

of the city of Denver, county of Arapahoe,

view, partly in section, showing my improved hub and the mannerofattachment of the spokes thereto. Fig. 3 is a detail, partly in section,of the hub,'showing the manner of attachment of the spokes thereto. Fig.4 is an end view of the hub, showing the ends of the bolts illustratedin Fig. 2. Fig. 5.is a view similar to Fig. 1, but showing the manner ofattachment of the spokes of the wheel when the hub is made of metal.Fig. 6 is an end view of the main hub portion, showing the slots thereinand spokes fitted into some of said slots. Fig. 7 is a longitudinalsectional view of my said hub when constructed of metal, showing thesame in detail and also the manner of attaching the spokes thereto andthe assemblage of the whole, together with one form of axle illustratedrunning therethrough. Fig. 8 is an end View of the entire hub.

My invention relates to hubs used in wheels having bowed spokes ofresilient material. As shown at 1, said spokes are preferably pivotallyattached to stirrups placed upon the inner side of the rim of the wheel,preferably by means of a bolt running through sides of the stirrup,around which the end of the spoke is curled, forming an eye.

I will first describe the construct-ion of my improved hub when made ofwood and afterward will describe the same when composed all of metal.The former is shown more particularly in Figs. 1 to 4 and the latter inFigs. 5 to 8.

In Fig. 2, 4indicates the round wooden hub, 5 the spokes fastenedthereto on one end thereof, and 6 the spokes entering thereinto andattached thereto at the other end of the hub. 7 indicates a bolt runningentirely through the hub, binding thereto the flanges 8, which by meansthereof are bound firmly to each end of the hub. Said anges 8 havecollars 9 projecting laterally from the central portion of the same,forming a-space through which the axle 10 of the vehicle passes. Thisaxle may be of any desired pattern. As shown at 11, this collar projectson the end side of the hub beyond the end of the axle and the axle-cap,protecting it from harm. Bolts 7 are made operative by their heads 12and the nut 13. After the flanges 8 have been fitted over the wooden hubthe bolts 7 are run through the flange on one end of the hub, throughthe wood, and through the opposite flange and the nuts 13 screwed home,whereby the whole is bou nd together as a firm and compact structure.The lianges 8 have on their inner side a rim 14, which encircles the endof the wooden part of the hub completely, except that at the point whereeach spoke enters the hub said rim is notched to allow said spokes topass therethrough. As shown, the several spokes are suitably attached tothe rim ot' the wheel and alternately connected with opposite sides ofthe hub-that is to say, (referring to Fig. 1,) While the spoke numbered15 will be brought to one end-of the hub, as indicated at 5, Fig. 2, thespoke numbered 16 will enter the hub at the end opposite to that wherethe spoke numbered 15 is attached, (designated at 6, Fig. 2.) Spokenumbered 17 will againbe attached to the same end of the hub as thatnumbered 15, and spoke'numbered 18, again alternating, will be attachedat the same endof the hub as the spoke numbered 16, and so on around thewheel.

The spokes are attached to the hub in the following manner: Each spokeis provided with an eye 19, which is formed by the end thereof simplybeing turned around into that shape. Passing through the lianges 8 atthe part marked 20 are the bolts 2l, which also pass through the eyes19. The nuts 22 holdF95 said boltsv in place, and the combination of thetwo assists in binding the structure together. Slots 23 are out in thewooden portion of the hub 4 at the required number of points on itscircumference, allowing the IOO spokes to enter from the rim of thewheel to be attached in place in the hub. These spokes are attached tothe hub in the following manner: The flanges 8 not being attached to thewooden part of the hub, the slots 23 are exposed to view from both endsof the hub, as well as places for the eyes 19. The spokes are simplyslipped into the slots and eye-spaces at their respective ends of thehub. The flanges 8 are then placed in position, the bolts 21 are drivenin through both flanges 8 into the wooden portion 4, and the nuts 22screwed home.

24 indicates the rubber or other tire to the Wheel, attached in anyordinary or desired manner.

When the hub is constructed entirely of metal, some variations in theseparts are necessary. Vthile any form of axle may he used in this hub, inthe drawings I have shown it with a Timken roller-bearing.

As part of my special hub construction I provide a cap 25, whichincloses the end of the hub and axle away from the body of the Vehicle.The screw threads 26 form the means of attachment of this cap to themain part of the hub. This main portion of the hub 27 is constructedentirely of metal and has projecting therefrom two annular flanges 28and 29, which project from the periphery of the hub at points adjacentto its ends. Said annular flanges are both provided with slots, as inthe wooden hub before described, having at the bases of said slots, nearthe center of the hub, holes drilled thereinto approximately the size ofthe eyes upon the spokes, which are inserted into said metal hub in thesame way as into the wooden one-that is to say, from the ends-by beingslipped into the slots in their straight portion, the eyes beinginserted into the round holes at the bases of the slots. Theconstruction of these slots is shown at 30, and the holes for the eyesat 31.

32 indicates the appearance of the end of the hub when the spokes are inposition, but before the flanges 8 are adjusted to their places at theends of the hub. To hold the spokes within the slots, I provide annularflanges or caps 33, which fit to the ends of the hubs at both ends,there being two to each hub. These flanges bear upon the central portionof the hub 27 at 34E and are retained in position at the bottom, wherethey rest upon said central portion of the hub, by the cap 25, beforedescribed, and the cap 35 at the other end of the hub. The cap 35 isscrew-threaded and fastens upon the main portion of the hub in a mannersimilar to the cap 25, but differs from it in having an aperture in itscenter for the passage of the axle. The upper part of these flanges orcaps 33 is held firmly in position bearing against the flanges 29 bymeans of the bolts 36, which run through the flanges 29 and flanges orcaps 33 and have heads 37 and nuts 38 to retain them in place. Theflanges 33 have the rim 14, the same as in the Wooden form of this hub,which is notched at various parts of its circumference for the admission of the spokes.

I am aware that many minor changes in the form and arrangement of theparts constituting the different parts of my invention maybe made andthat minor changes of construction in the same may be made withoutdeparting from the nature and spirit thereof.

Having thus described my invention, What I claim, and desire to secureby Letters Patent, is-

1. A hub adapted to receive spokes at points .adjacent to its ends,having on its periphery raised portions formed integral therewithcontaining grooves for the reception of the spokes, caps to hold thespokes in said grooves, and caps 25 for retaining said caps in place,substantially as described.

2. The combination of main hub portion having flanges, grooves in saidflanges, spokes tting therein, caps to retain said spokes in saidgrooves, and screw-threaded caps to hold said first-mentioned caps inposition, substantially as described.

3. A hub comprising a central core, having grooves in the ends thereofextending from the periphery a suitable distance toward the centerthereof, with holes at the inner ends of the same, adapted to receiveand contain flat resilient spokes, having eyes formed on their innerends adapted to fit in said holes.

4. A hub comprising a central core having raised portions on itsperiphery adjacent to its ends, grooves in said raised portions adaptedto receive and contain flat resilient spokes, said grooves terminatingin holes adapted to receive and contain eyes formed on the ends of saidspokes.

5. A hub comprising a central core, grooves in said hub adjacent to itsends adapted to receive and contain flat spokes, and a flange TOO or caphaving a notched or recessed rim lat,

adapted to overlap a part of said central core, and in said recesses toafford bearing-surface for said spokes.

6. A hub comprising a central core having grooves therein adapted toreceive and contain resilient spokes having eyes on the inner endsthereof fitting into holes at the inner ends of said grooves and boltspassing through said eyes and into the main hub portion.

In testimony whereof I have hereunto affixed my signature, in thepresence of two Witnesses, this 22d day of April, 1901.

JOHN G. WORKING.
